"How would you raise your child, if you knew that one day their turn will come to hold a rifle?" In one of the most acclaimed shows in the Edinburgh Fringe 2017, Israeli actor Niv Petel's Knock Knock weaves a poignant and heartfelt tale about the effects of conscription on everyday life for a single mother and her only son. Told with innovation and imagination through minimal sets and props, the physical mono-drama evokes sympathy through laughter juxtaposed with a deep emotional subtext. Niv Petel delivers a controlled yet moving performance, making both roles come to life through nuances of emotions and telling an intimate story about parenthood, friendship, love and sacrifice.
